Simufilam (PTI-125) (hydrochloride) is a low toxicity, orally active filamin A (FLNA) activator. Simufilam (hydrochloride) preferentially binds altered FLNA and restores its native conformation, restores receptor and synaptic activities, reduces its a7nAChR/TLR4 associations and downstream pathologies. Simufilam (hydrochloride) can be used for the research of Alzheimer's disease.

Simufilam (1 pM~1 nM) (hydrochloride) dose-dependently improves NMDA/glycine-induced Arc expression.
Simufilam (1 nM, 1 hour) (hydrochloride) largely restores filamin A to its native conformation and is effective in normalizing receptor activities in AD frontal cortices. Simufilam (hydrochloride) dose-dependently reduces Ab42-induced FLNA coupling to a7nAChR and TLR4 in both Ab42-treated control and AD hippocampus. Simufilam (hydrochloride) reduces Ab42's binding affinity for a7nAChR, thereby prevents Ab42's signaling and further accumulation on a7nAChRs.
